Ten lines times about 200 messages per day each is 2,000 daily opt-in touches. That scale only works with real UK carrier eSIMs, not a pile of 5sim virtual numbers that die on registration.
Procurement math
| Item | Qty | Notes |
|---|---|---|
| BuyUKeSIM eSIM | 10 | $25 each, crypto, no KYC at checkout |
| Android phones | 10 | Mid-range, one primary device per line |
| Warm-up period | 2 weeks per line | Stagger starts by 3 days |
| Daily outbound cap | ~200 per line | After warm-up complete |
Staggered launch
- Week 1: activate eSIM lines 1 to 3, warm only
- Week 2: add lines 4 to 6, lines 1 to 3 light outreach
- Week 3: add lines 7 to 10, prior lines at 50% volume
- Week 4+: full rotation across all ten
Per-line warm-up detail: warm-up guide. Register each: WhatsApp setup. Never VOIP: virtual failures.
Ops rules
- CRM tags which line owns which lead (no double contact)
- Shared template library but unique first names
- Pause entire fleet if any line gets restricted
- Top-up all lines on same calendar reminder (~6 months)
Disclaimer
2,000 messages/day is not permission to spam. Every recipient must opt in. WhatsApp ToS applies to all ten lines.
